Including code and plots

You can embed code as normal, for example:

##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Let’s clean up the format of that output instead of using the standard R output:

summary(cars) %>%
  kable(col.names = c("Speed", "Distance"),
        row.names = FALSE) %>%
  kable_styling(bootstrap_options = "striped",
                full_width = FALSE) %>%
  row_spec(0, bold = TRUE) %>%
  column_spec(1:2, width = "1.5in") 

In a study from the 1920s, fifty cars were used to see how the speed of the car and the distance taken to stop were related. Speeds ranged between 4 and 25 mph. Distances taken to stop ranged between 2 and 120 feet, with the middle 50% falling between 26 and 56 feet.

You can also embed plots as normal, for example:

Take note of the default code chunk options in the setup code chunk, and adjust individual code chunk options as needed. for example, unlike the rest of the Rmd files we worked in this semester, the default code chunk option is echo = FALSE, so you will need to set echo = TRUE for any code chunks you would like to display in the blog.

Including links and images/videos

You can include links and there are a few ways to embed images! Both options for embedding images below can be used interchangeably. They both work for png, pdf, jpg, and even gif formats, and both support filepaths that are either URLs (for videos, you can include links to any valid YouTube or Vimeo URLs; see here for more details) or point to a location within your project directory.

Option 1: Markdown approach

Option 2: Code chunk approach

This is also figure caption

Including equations

Equations may be needed if you are explaining a new technique or perhaps providing some other relevant formulas in your exposition. There are two ways to include equations:

• Inline: \(b \sim N(0, \sigma^2_b)\)
• Display-style (displayed on its own line): \[\frac{\sigma^2_b}{\sigma^2_b + \sigma^2_e}\]

For typesetting equations appropriately, take a look at the Symbols in math mode section of this cheat sheet (or do some extra Googling—there are many resources).

Embedding Shiny apps

To embed Shiny apps, you must publish your Shiny app to shinyapps.io (or the Amherst Shiny server). Make sure the YAML header includes the line self_contained: false. Then you can use this code chunk below, adjusting the width and height as needed to accommodate your Shiny app.

To deploy an app to the Amherst Shiny server, do the following:

1. Go to r.amherst.edu and log in.
2. Go to your Home directory on the server and create a new folder called ShinyApps if it doesn’t already exist (make sure you match the case).
3. Set up your blog repo on the server using the directions from the first week of the semester (creating tokens to authenticate, then creating a new Version Control project, etc.).
4. Once you’ve set up and pulled your blog repo on the server, copy the completed Shiny app folder to the ShinyApps folder in your Home directory.
5. Your app has now been deployed! Run it by going to r.amherst.edu/apps/your-user-name/your-app-folder-name.
